The DSM is not shipped with a package management. If you want to add functionality such as 'vim' or 'sudo', then install the 'ipkg' package manager first.

This guide was written for DSM 4.3, but it also applies identically to DSM 5.1.

The following bootstrap files need to be run for the different versions of DSM hardware. Check the CPU version if in doubt as root:

# cat /proc/cpuinfo

Copy the file to the DSM or get it directly from the command line, then make it executable and run it. The example below is for the i3 bootstrap, replace the file name accordingly:

# wget http://ipkg.nslu2-linux.org/feeds/optware/syno-i686/cross/unstable/syno-i686-bootstrap_1.2-7_i686.xsh
# chmod +x syno-i686-bootstrap_1.2-7_i686.xsh
# ./syno-i686-bootstrap_1.2-7_i686.xsh

Reboot the VM or NAS. Change the path of your user and root as described in Configuration.

To install apps, run the following:

ipkg update
ipkg install <app>

# ipkg install sudo

After installation, run visudo and uncomment the line starting with '%sudo' which defines rights for members of the sudo group. Then add the sudo group to /etc/group.

# visudo
%sudo ALL=(ALL) ALL

# vi /etc/group
sudo:x:27:<user>

Change the shell prompt of your user and root as described in Configuration.

# ipkg install vim

To fix the broken arrow keys in insert mode in vim, change the vim default config as follows:

$ vi ~/.vimrc
set nocompatible

Or better, set the system wide configuration file vimrc, or copy the example vim config file. First, find where the system wide config file is located:

$ vim
:echo $VIM

For DSM 4.3 / ipkg, the location is /opt/share/vim, the example config file is located in the same directory:

# cp /opt/share/vim/vimrc_example.vim /opt/share/vim/vimrc

For Debian Wheezy, the location is /usr/share/vim pointing to /etc/vim, the example config file is located in /usr/share/vim/vim73:

# cp /usr/share/vim/vim73/vimrc_example.vim /usr/share/vim/vimrc

Instead of copying the configuration file template, you can also just add syntax highlighting to /etc/vim/vimrc:

if has("syntax")
  syntax on
endif
